Masja [62]3 years ago

Step-by-step explanation:

P varies to d²

F=K/d²

where K is the constant

6=k/6²

6=k/36

K= 216

we write the equation

F=k/d²

we substitute

F=216/3²

F=216/9

F= 24

Answer:

F = 24

Step-by-step explanation:

Given that F is inversely proportional to d² then the equation relating them is

F= \frac{k}{d^2} ← k is the constant of proportion

To find k use the condition F = 6 when d = 6 , then

6 = \frac{k}{6^2} = \frac{k}{36} ( multiply both sides by 36 )

216 = k

F = \frac{216}{d^2} ← equation of proportion

When d = 3 , then

F = \frac{216}{3^2} = \frac{216}{9} = 24

A skateboarder went a kilometer in 3 minutes with the wind, and returned in four minutes against the wind.
inn [45]

Step-by-step answer:

Answer to problems of this kind is the reciprocal of the harmonic mean of the time required.

We need to find the average of the speeds, not the average of the time.

The respective speeds are 1/3 and 1/4.

The average of the speeds is therefore (1/3+1/4)/2 = 7/24  (harmonic mean of the time taken).

The time required is therefore the reciprocal of the unit speed,

T = 1/(7/24) = 24/7 = 3 3/7 minutes, or approximately 3.43 minutes.

Suppose demand d for a company's product at cost x is predicted by the
11111nata11111 [884]

Answer:

0.36x ² + 815.04x + 11,340

Step-by-step explanation:

Revenue = price × quantity

p(x) = x+14

d(x) = 0.36x + 810

Revenue = price × quantity

= (x + 14) * (0.36x + 810)

= 0.36x² + 810x + 5.04x + 11,340

= 0.36x ² + 815.04x + 11,340

Company's revenue = 0.36x ² + 815.04x + 11,340

Find the common ratio for the geometric sequence for which a1=3 and a5=48
Rama09 [41]

The ratio is common, so you could write:

a1 * r^4 = a^5 (you do r^4 because there are 4 times you need to multiply by the ratio to get from a1 to a5)

Plug in the values:

3 * r^4 = 48

Divide by 3:

r^4 = 16

Take the fourth root of both sides:

r = 2

The common ratio is 2.

Find the slope of the line passing through the given points (-5, 14) and (-1,2).
dexar [7]
So your formula is y1 - y2 divided by x1 - x2. Start off with the -5, 14 as your x1 and y1 because its the biggest out of the other one. So do 14 - 2 = 12 so thats your top part and -5 - -1 which is -4 so your fraction will be 12/-4 or you have -3 as a whole number
